Article defines on the efficiency of the internal combustion engine and presents the analysis based on originally conducted studies. The actual driving cycles car are described as well. The increase in overall engine efficiency is sought after by all engineers dealing with engine construction. Based on the formulas for power and efficiency of theoretical cycles, the following statements may be made: - efficiency depends on the compression ratio - power depends on the charge in the cylinder - efficiency is affected by the amount of heat loss in fumes and engine cooling Power regulation in petrol engines is carried out by changing the throttle position in the inlet system; in this way, there is a possibility of affecting the effective compression ratio value. The application of the compression ratio that has been increased constructionally in the engine will, on one hand, bring about the increase in the theoretical efficiency, but, on the other hand, require a system for pressure control at a higher engine load in order to prevent engine knocking. For the purposes of the article there was carried out a number of studies and compiled results, and on their basis determined what have a major impact on the efficiency of the vehicle and the extent to which it changes.
